When you multiply fractions does the denominator change

Ede4ka [16]

Answer:

Step-by-step explanation:

When multiplying fractions, simply multiply the numerators together and then multiply the denominators together.

This works whether the denominators are the same or not.

(e.g) if you multiply the fractions 3/2 and 4/3 together, you get 12/6.

If $x$ and $y$ are positive real numbers for which $(x + y)^2 + (x - y)^2 = 10$ and $(x + y)^4 + (x - y)^4 = 98$, what is the va

slava [35]

$(x+y)^2+(x-y)^2=10$
$\implies 2x^2+2y^2=10$
$\implies x^2+y^2=5$
$\implies (x^2+y^2)^2=x^4+2x^2y^2+y^4=25$

$(x+y)^4+(x-y)^4=98$
$\implies 2x^4+12x^2y^2+2y^4=98$
$\implies x^4+6x^2y^2+y^4=49$
$\implies 25+4x^2y^2=49$

$4x^2y^2=24$
$\implies x^2y^2=6$
$\implies xy=\sqrt6$
